초록
All-ceramic zirconia implant has significant attention as a substitute for titaniumimplant because of its excellent aesthetic properties and biocompatibility, but it requires improvedbioinertness and surface smoothness. This study attempted to improve the bioactivity and surfaceroughness of zirconia substrate by bioactive wollastonite coating. A continuous process for slurrypreparation, spin coating, and post-sintering was used to modify porous zirconia substrate andcontrolled the repeated coating times and chemical composition. Wollastonite slurry for coatingcontrolled the solid loading, pH, and dispersant to adjust the slurry viscosity. A dense coatinglayer was obtained by slurry coating and post-sintering processes. The coated layer'smicrostructural evolution, phase composition, and surface roughness were observed by SEM andXRD investigation, indicating that the coated layer's physical and biological properties dependedon the slurry condition and coating times. The coating surface had good bioactivity comparedwith pure zirconia substrate, indicating that slurry coating of wollastonite was available toenhance the bioactivity of bioinert-zirconia substrate.
